### How many drops of water are in a gallon?

According to the U.S.G.S. the average size of water droplet from
a bathroom or kitchen faucet is about 1/4 of a milliliter (or CC),
or 4,000 drops per liter; and about 0.0169 fl oz or 15,140 drops
per gallon.
Some science measurements from droppers measure a drop much
smaller, at 1/20th of a CC per drop, making the number of drops per
gallon much higher.
20 drops/CC X 30 CC/fl oz X 128 fl oz/Gal = 76800
drops/gal
In the end, it depends on the size of the drop as to how many
drops there are in a gallon. For household leaks, 3-4 drops/CC is
much more likely than 20-24 drops/CC that is often cited for
scientific purposes.
